Bug report

Bug description:

import threading

def main():
    r = threading.RLock()
    print(f"{r = }")
    t = threading.Thread(target=r.acquire)
    t.start()
    t.join()
    print(f"{r = }")
    print(f"{r.locked() = } at {hex(id(r))}")

if __name__ == '__main__':
    main()

Output is:

r = <unlocked _thread.RLock object owner=0 count=1 at 0x105a98720>
r = <locked _thread.RLock object owner=6106329088 count=1 at 0x105a98720>
r.locked() = False at 0x105a98720

Error is located at:

cpython/Lib/threading.py

Lines 238 to 240 in 28625d4

	def locked(self):
	"""Return whether this object is locked."""
	return self._count > 0

The return instruction must be: return self._block.locked().

I can submit a PR quickly.

CPython main branch, 3.14

Didn't we already have a report for this one actually?

EDIT: It was related but not this one in particular: #132561.
